YAP knockout causes BCPAP and KI cells to arrest at the G0/G1 phase and decreases expression of c-Myc and Foxo3a expression while increasing p21 and p27 expression in BCPAP cells. A. Cell sorting of propidium iodide stained BCPAP or KI cells treated with siRNA Con or siRNA YAP. B. Quantification of the proportion of BCPAP and KI cells in G0/G1, S, and G2/M phases. C. Western blots of c-Myc, Foxo3a, p21 and p27 in siRNA Con and siRNA treated BCPAP cells. The graphs represent quantification of the respective protein signal from the Western blots. (*, ** represent P<0.05 and P<0.01 respectively compared with siRNA Con, n=3 independent experiments).
